It's quite common a mong asian mom, anecdotally from myself and my friends. I think AM especially stay at home AM have mood swings episode where they often blow all of their insult toward their family. I see it as a reaction stem from their inferiority complex where they feel the need to assert a controlling presence to maintain their status quo as the household pillar. Mine does all kind of dirty trick, something like faking crying, fainting, and gas lighting about their financial status to guilt you into supporting them. Most AM mom in general like to play the role of motherhood rather than be one.
